[asterisk-users] PRI progress codes.

[Wai Wu]

I assume in this case, you are making the out of the PRI line. Well, that's exactly how PRI works. What you should do is look at the progress code and determine what the call status are (busy, disconnected number, moved number, etc) and play a proper message for the customer. As for the second case, it is not common for PRI lines hold up the call with dead air for 15 to 30 seconds. In my 20 years of dealing with the carriers, it is usually caused by the original PRI network is routing the call to a different network. Usually a different provider and mostly through an analog interface. In this case, there is not a thing you can do about it. 

Welcome to the true world of telecommunications.

Anyone know how to let asterisk deal with the progress codes coming
from the carrier? The problem I am having is when a customer calls an
invalid number the carrier tells me the call is invalid via a progress
code but doesn't route me to a recording (this number is invalid).
Instead they hang up on me causing a fast busy or sometimes hold up
the call with dead air for 15 to 30 seconds then a fast busy. I am
working with the carrier to get this fixed but its not going easy.
Is there anyway when asterisk sees the progress code to cancel the
dial and playback a message mapped to the progress code type.

Any help on this would be appreciated.
